🌱 Vegetarianism and Veganism: The Difference and How Not to Harm Yourself

Two similar paths, but with different "pitfalls"

Many people confuse vegetarianism and veganism — and for nothing: these are two different diets with different risks. While vegetarians still get eggs and milk, a vegan cuts out all animal products. Let's look at where the line runs and what's important not to miss.

🔬 The difference

Vegetarians cut out meat and fish but keep eggs and dairy. Vegans remove everything animal: meat, fish, eggs, milk, and often honey. The line runs exactly along "animal products."

  • Vegetarian: no meat and fish.
  • Keeps eggs and milk.
  • Vegan: no animal products.
  • Often no honey either.
Why it matters: the stricter the diet, the more "gaps" need closing.

Nuance: there's also pescetarianism — with fish.

⚠️ Main risks

  • B12 — only in animal foods.
  • Iron from plants absorbs worse.
  • Calcium — if no dairy.
  • Protein — with a monotonous diet.
Important: B12 is a must for vegans, recommended for vegetarians.

🩸 Tests

Once a year, it's worth checking B12, ferritin, homocysteine and vitamin D. This matters especially for vegans and vegetarian women of reproductive age.

  • B12 in blood.
  • Ferritin (iron stores).
  • Homocysteine.
  • Vitamin D.
